That's why we call them flavors. People like certain flavors. It doesn't mean the nutrition is any different or that you need to always use only whatever flavor is somebody else's favourite. The lovely thing about Linux is the freedom to choose and to try different things to find what works best for you personally. There's no organization trying to shove certain tools and principles down your throat for profit. It's literally just personal preferences and they're all equally valid choices. We try to make recommendations on things that might be easier to grasp or might suit a person's situation better but really they're all just flavors and they're all good for the people who like those flavors.
